Chronic obstructive pulmonary disease (COPD) refers to two lung diseases, chronic bronchitis and emphysema, that are typically caused by smoking and result in limited airflow. The document discusses the definition, causes, symptoms, diagnosis, and management of COPD. It notes that COPD is the 4th leading cause of death and involves inflammation and narrowing of the airways leading to shortness of breath. Treatment focuses on improving ventilation, removing secretions, managing complications, and improving overall health.
2. COPD is also known as chronic obstructive
lung disease (COLD), chronic obstructive
airway disease (COAD), chronic airflow
limitation (CAL) and chronic obstructive
respiratory disease (CORD)
Chronic obstructive pulmonary disease (COPD)
refers to chronic bronchitis and emphysema, a
pair of two commonly co-existing diseases of
the lungs in which the airways become
narrowed. This leads to a limitation of the
flow of
air to and from the lungs causing
shortness of breath.
3. In
COPD, less air flows in and out of the
airways because of one or more of the
following:
The airways and air sacs lose their
elastic quality.
The walls between many of the air sacs
are destroyed.
The walls of the airways become thick
and inflamed.
The airways make more mucus than
usual, which tends to clog them.
5. It is the 4th leading cause of mortality and
12th leading cause of disability in the
united states.
In 2020 COPD is the 3rd leading cause of
death.
6. 1)Smoking
2) Occupational exposures- exposure to
workplace dusts found in coal mining, gold
mining, and the cotton textile industry and
chemicals such as cadmium, isocyanates, and
fumes from welding have been implicated in
the development of airflow obstruction.
3) Air pollution
4) sudden airway constriction in response to
inhaled irritants,
5) Bronchial hyperresponsiveness, is a
characteristic of asthma.
7. 6)Genetics-Alpha 1-antitrypsin deficiency
is a genetic condition that is responsible
for about 2% of cases of COPD. In this
condition, the body does not make enough
of a protein, alpha 1-antitrypsin. Alpha 1-
antitrypsin protects the lungs from
damage caused by protease enzymes, such
as elastase and trypsin, that can be
released as a result of an inflammatory
response to tobacco smoke.

9. Abnormal inflammatory response of the
lungs due to toxic gases.
Responseoccurs in the airways
,parenchyma & pulmonary vasculature.
Narrowing of the airway takes place
Destruction
of parenchyma leads to
emphysema.
10. Destruction of lung parenchyma leads to an imbalance
of proteinases/antiproteinases.
(this proteinases inhibitors prevents the destructive
process)
Pulmonary vascularchanges
Thickening of vessels
Collagen deposit
Destruction of capillary beds.
Mucus hypersecretion(cilia dysfunction,airflow

Chronic cough and sputum production
11. Chronic cough
Sputum production
Wheezing
Chest tightness
Dyspnoea on exertion

Respiratory insufficiency
Respiratory infections
Barrel chest- chronic hyperinflation leads
to loss of lung elasticity.
12. 1) Bronchitis
2) Emphysema
Bronchitis :-
Bronchitis (bron-KI-tis) is a condition in which
the bronchial tubes become inflamed.
13. acute (short term) and
chronic (ongoing).
Infections or lung irritants cause acute
bronchitis.
Chronic bronchitis is an ongoing, serious
condition. It occurs if the lining of the
bronchial tubes is constantly irritated and
inflamed, causing a long-term cough with
mucus.
14. Chronic bronchitis:
It is defined as the presence of cough and
sputum production for atleast 3 months.
15. Irritants irrritate the airway
Excess mucus production
Inflammation
Cause the mucus secreting glands and goblet cells to
increase in number.
Ciliary function is reduced.
More mucus production
Bronchial walls become thickened and lumen narrows and
mucus plug the airway
16. Alveoli adjacent tto the bronchioles may
become damaged and fibrosed.
Alter function of alveolar macrophages.

17. sore throat,
fatigue (tiredness),
fever, body aches,
stuffy or runny nose,
vomiting, and
Diarrhea
persistent cough
cough may produce clear mucus
shortness of breath
18. coughing,
wheezing, and
chest discomfort.
The coughing may produce large amounts
of mucus. This type of cough often is
called a smoker's cough.

the flu
•Whether you smoke or spend time around
others who smoke
•Whether you've been exposed to dust,

29. Definition:-Emphysema is defined as
enlargement of the air spaces distal to
the terminal bronchioles, with
destruction of their walls of the alveoli.
Pathology :
As the alveoli are destroyed the alveolar
surface area in contact with the
capillaries decreases.
Causing dead spaces (no gas exchange
takes place)
30. Leads to hypoxia.
In later stages:
CO2 elimination is disturbed and
increase in CO2 tension in arterial blood
causing
Respiratory acidosis
(Decrease pulmonary blood flowis
increased forcing the RV to maintain high
B.P. in PA.)
31. Centrilobular-Therespiratory bronchiole
(proximal and central part of the acinus)
is expanded. The distal acinus or alveoli
are unchanged. Occurs more commonly in
the upper lobes.
32. Panlobular-The entire respiratory acinus,
from respiratory bronchiole to alveoli, is
expanded. Occurs more commonly in the
lower lobes, especially basal segments,
and anterior margins of the lungs.
